Laptop not working well with 10.10 on battery

Ever since 10.10 64 bit it seems my asus k50id locks up whenever i try to boot using my battery, or whenever i unplug my power and switch to battery it freezes. This never happened in 10.04, is there any possible way i can solve this or is it just a bug for now? oddly enough, i can login with safemode but it usually locks up after 1-5 minutes. this is a major problem because i use my laptop for writing notes in school and now this renders my laptop completely useless. please help this is urgent. thanks!
